A catching device of a needle for a safety syringe includes a tube containing an inserted connection foot of the needle or an inserted hub adapted for fitting of the connection foot of the needle where in the connection foot of the needle or in a hub a cylindrical cavity with a conical inclination is created and the tube. An inserted plunger fitted on the front face with a conical adapter with a forward-running cylindrical projection and where at the same time in the foot of the needle or in the hub adapted for fitting of the connection foot of the needle a transversal slot is created. The inserted plate is designed as a catching plate that has a circular opening in its centre where the perimeter edge of this circular opening is adapted to increased elasticity in the radial direction by creating of an inner blade (3410) in the form of a conical skirt, getting narrower in the direction outwards from the syringe tube.
A catching device of the needle (4) for a safety syringe comprising:
A safety syringe containing a needle catching device wherein on an inner side of a syringe tube (1) an inner perimeter projection (12) is created before a front edge of the plunger (2) while this place corresponds to such a position of the plunger (2) in the cavity of the syringe tube (1) where a perimeter edge (2101) of a base (210) of a conical adapter (21) of the plunger (2) is found before a catching plate (34) and at the same time the front end of a cylindrical projection (212) of this conical adapter (21) is found behind the catching plate (34).
